Axis-symmetric problem of the radiation transport in a spherical shell. I. The characteristics of the transfer equation

S. V. Maksakova, T. A. Sushkevich

Abstract: The characteristic equations of the differential transfer operator with the partial derivatives for a spherical shell with the axial symmetry deduced. The geometric interpretation for the first integrals in four-dimensional phase space is given.
